Preferably, said rotor is divided into 16 equal portions in equal size.
As further improvement of the present invention, between said bearing seat and support, also be provided with the adjusting jackscrew, this regulates the height of jackscrew adjustable axle bearing.
The present invention also provides a kind of large rotor to do statically balanced method, may further comprise the steps:
1. fixed rotor: at first support is positioned on the surface level, and bearing seat is installed on the support, the two ends that will be fixedly arranged on the rotor coupling shaft of rotor axis then are installed in respectively on the bearing seat, through the regulating shaft bearing rotor coupling shaft are horizontal;
2. with the rotor circumference five equilibrium: the end face at rotor is divided into some even number equal portions with it by central angle, and makes mark;
3. do balancing weight and connect wire drawing; Connect wire drawing with one and place outside the rotor circumference face, and establish a standard balancing weight at an end that connects wire drawing, the other end connects a tautness meter, and the standard balancing weight is not contacted with rotor with tautness meter;
4. test: a pair of equal portions point that rotor is relative places horizontal level; The wire drawing two ends that are connected that keep connecting balancing weight and tautness meter are in vertical direction respectively, read tautness meter registration and record when treating rotor balancing, and the like; Accomplish the measurement and the record of other relative equal portions points; Find out maximum difference at last, i.e. the emphasis of rotor and dubbing most, and the counterweight of additional respective quality dubbing most to rotor;
5. balance check: repeat above-mentioned steps, accomplish up to the rotor static balancing stand the test.
Preferably, an end face of said rotor is divided into 16 equal portions with it by central angle.
The invention has the beneficial effects as follows: through being divided into the rotor circumference end face some even number equal portions and making a mark; Place on the rotor circumference face connecting wire drawing then, a pair of suitable two equal portions point of rotor is laid respectively on the horizontal direction, the two ends that connect wire drawing connect standard balancing weight and tautness meter respectively; Can judge the equilibrium state of 2 equal portions points of rotor horizontal direction through the registration of tautness meter; Then and the like, can check other equilibrium conditions respectively to equal portions point, can make indemnifying measure according to the check structure at last; This method is not only simple, accurate, and can save manpower and time greatly.This balance can reach more than the G6.3 level of " GB 9239-1988 balance quality of rigid rotor is allowable unbalanced definite ", can satisfy various balance requirements.This method can the large-scale outside diameter 2m-5.3m of convenient and swift accurate realization rigidity rotor static balancing, is applicable to the interior rigidity rotor of supporting powder concentrators, fan rotors such as Vertical Mill, pipe mill.
